Im no pro gamer anything, and also started playing on expert.
Now, however, im playing with mods to make it harder on a revamped master difficulty (which is statistically 2 times harder than vanilla master)
But after a while you discover the tricks and can pretty much handle everything if played correctly, then im talking about any ranged character with a follower/atronach to tank the enemies.
Also the 100% mana reduction enchants for destruction is way too overpowered (stunlocking) and in my opinion shouldnt be achieved in the game, but the game allows you to have it so its kinda "hard" not to take it when you know you can.
I was wondering your view on this and how you handle this issue
